KATHERINE K. MARCEL, MD
Board Certified Internal Medicine
WELCOME TO MARCEL CLINIC
At Marcel Clinic, we focus on promoting health and preventing diseases by meeting the needs of our patients efficiently, accurately and proactively. To accomplish these focus areas, we advise our patients to have annual checkups, early detection screening, and healthy lifestyle choices. Our team believes that these measures improve the overall well-being of our patients.
PERSONALIZED HEALTHCARE MEETS ROYALTY STANDARDS—EXPERIENCE THE DIFFERENCE
Marcel Clinic focuses on a healthcare model called Concierge Medicine, where patients pay an annual fee (or retainer) to their primary care provider in exchange for a wide range of special benefits. Some of the benefits of Concierge Medicine include convenient and enhanced access, personalized care, and various services beyond what is typically offered in a common primary care setting. Dr. Marcel and the Marcel Clinic Team aim to provide a more patient-centered and comprehensive healthcare experience. Visit our Concierge Medicine Clinic in Baton Rouge today!

I absolutely love Dr. Marcel! The first time I bragged about how wonderful she is to everyone I know! She is so down to earth & actually listens to you, rather than looking at the computer the whole time. She communicates with you on MyChart 7 days a week. If you’re looking for an Internist/Primary Care Doctor, she’s the best! Her nurse and other staff members are amazing too!
